Problems solved by technology

[0006] However, since the user of the spliced ​​electrophoretic display panel views the image displayed on the electrophoretic display layer 130 through the first substrate 110, the user can easily find that there is a gap at the junction of the spliced ​​electrophoretic display panel.
In other words, it is very easy for the user to find that the junction of the spliced ​​electrophoretic display panel is uneven, which seriously affects the user's perception of the appearance of the spliced ​​electrophoretic display panel.

[0049] figure 2 It is a schematic cross-sectional view of the electrophoretic display unit according to the first embodiment of the present invention. Please refer to figure 2 , The electrophoretic display unit 200 of this embodiment includes a first substrate 210 , a second substrate 220 , an electrophoretic display layer 230 and a sealant 240 . The second substrate 220 is disposed below the first substrate 210 . The electrophoretic display layer 230 is disposed between the first substrate 210 and the second substrate 220 . The frame glue 240 is connected with the electrophoretic display layer 230 , the first substrate 210 and the second substrate 220 and surrounds the electrophoretic display layer 230 .

[0050] In this embodiment, the first substrate 210 may include a first base 212 and a common electrode 214 covering the first base 212 . The first substrate 210 in this embodiment is, for example, a light-transmitting substrate, and its material can be glass, quartz, ...

[0061] Figure 4 It is a schematic cross-sectional view of the spliced ​​electrophoretic display panel according to the second embodiment of the present invention. Please refer to Figure 4 The structure of the spliced ​​electrophoretic display panel 2000a of the present embodiment is similar to that of the spliced ​​electrophoretic display panel 2000 of the first embodiment. 220a is substantially aligned.

[0062] In the spliced ​​electrophoretic display panel 2000a of this embodiment, the area of ​​the first substrate 210 is also larger than the area of ​​the second substrate 220, the edge 210a of the first substrate also exceeds the edge 220a of the second substrate, and the outer edge 204a of the sealant not beyond the edge of the first substrate 210a. Therefore, in this implementation, each first substrate 210 may also be closely connected to adjacent first substrates 210 .

[0063] Therefore, when the user views the display screen through the display surface S compos...

Please refer to Figure 5 The structure of the spliced ​​electrophoretic display panel 2000b of this embodiment is similar to that of the spliced ​​electrophoretic display panel 2000 of the first embodiment. The edge 220a of the second substrate is aligned; the sealant 240 of this embodiment is connected to the side of the second substrate, and the sealant 240 further covers a part of the outer surface 220b of the second substrate.

[0066] In this embodiment, the edge 240a of the sealant is also substantially aligned with the edge 210a of the first substrate. Each first substrate 210 is also tightly connected to adjacent first substrates 210 . That is to say, in the spliced ​​electrophoretic display panel 2000b of this embodiment, the unevenness of the seams C' between the electrophoretic display units is not eas...

Abstract

The invention discloses a spliced ​​electrophoretic display panel, which includes a plurality of electrophoretic display units arranged in an array and connected to each other. The electrophoretic display unit includes a first substrate, a second substrate, an electrophoretic display layer and a sealant. The second substrate is disposed below the first substrate. At least one edge of the first substrate extends beyond an edge of the second substrate. The electrophoretic display layer is arranged between the first substrate and the second substrate. The user watches the image displayed on the electrophoretic display layer through the first substrate. The frame glue is connected to the electrophoretic display layer, the first substrate and the second substrate, and surrounds the electrophoretic display layer. In these electrophoretic display units, each first substrate is respectively connected to one or more adjacent first substrates.

Description

technical field [0001] The present invention relates to a display panel, and in particular to an electrophoretic display panel. Background technique [0002] With the vigorous development of flat panel display technology, users not only have requirements for the performance of the display panel, but also have higher expectations for its aesthetic appearance. In order to meet the needs of users, many display panel manufacturers have begun to develop slim-board flat display panels. [0003] Common flat display panels include liquid crystal display panels, plasma display panels, electrophoretic display panels, and the like. Taking the electrophoretic display panel as an example, its cross-sectional schematic diagram is as follows figure 1 shown in . Please refer to figure 1 A known electrophoretic display panel 100 (100') includes a first substrate 110, a second substrate 120, an electrophoretic display layer 130 located between the first substrate 110 and the second substr...
